look up any word, like donkey punch:
 
1.
- to smoke marijuana. It is used during casual conversation in attempt to determine if a person also burns trees, because only a fellow tree burner would know what the speaker is talking about.
Also used when inquiring about products.
"Hey man, do you burn trees?"
"Um.. yeah, when the time is right"
"Wanna come up and blaze?"

"Ring"
"Hello?"
"I'm interested in trees"
"Can't help you today man, sorry"
